OPTIMASS 7 OPTIMASS 7000
Note:
For additional temperature limits in hazardous area applications, reference should be made to
the publication “
Guidelines for the use of Coriolis Meters in Hazardous Areas”.
Where meters are mounted in direct sunlight, it is recommended that a sunshade is installed.
This is particularly important in countries with high ambient temperatures!
The maximum differential temperature between the process and ambient temperature without
insulation is 130°C or 266°F for Titanium and 80°C or 1 76°F for Hastelloy, Stainless Steel and
Tantalum meters.
7.3 Pressure Equipment Directive (PED) Requirements.
To comply with the requirements of the PED in Europe, the following information is provided to
assist the plant engineer in installing the meter.
Measuring tube: Sealing Faces:
Titanium Grade 9 Titanium Grade 2
Hastelloy C22 Hastelloy C22
Stainless UNS 31803 Stainless UNS 31803
Tantalum grade RO5255 Tantalum grade RO5255
The outer cylinder 304 / 304L is dual certified (Optional outer cylinder of 316 / 316L). This also
applies to PED certified housings.
Wiring feedthrough is made of Epoxy.(or PEEK) with 2 ’O’ ring seals of FPM / FKM &
Hydrogenated Nitrile
Flanges all 316 / 316 L dual certified.
Optional heating jacket 316 / 316L.
Note: The outer cylinder is in contact with heating medium
7.1 Specific Installation Guidelines
• Tighten flange bolts evenly.
• Observe min and max pipe end loads at the end of this section.
The use of reducers at the flanges is allowed but extreme pipe size reductions should be avoid-
ed. This is to prevent the possibility of cavitation and degassing.
There are no additional installation requirements for the OPTIMASS 7000 sensors. Fixing of
flexible hoses directly on the meter is allowed.
7.2 Ambient/Process Temperatures
The specified and approved ambient and process temperatures MUST be observed.
